There’s a lot of evidence to find in Battlefield Hardline’s single player campaign, and doing so will unlock weapons and perks. Most importantly, once you collect all the evidence for a particular Case File, you’ll unlock trophies and achievements.

Most of the evidence is easy to find as you have a handy gadget to help you. Press R1/RB to bring up the scanner, which will tell you the general direction to look in and how many pieces of evidence there is to find in the location you’re in. When it’s not in use you’ll feel it rumble briefly when you’re close to evidence, so if it goes off during a shootout, make sure you clear the area before hunting down the evidence.

The three trophies/achievements you’ll earn are:

Keep Digging, Detective: Complete Any Case File

True Detective: Complete 3 Case Files

World’s Greatest Detective: Complete All Case Files

Below you’ll find all the evidence in every single-player mission, and which Case File is belongs to.
